* Discovery Information

It was detected by the PIXY system as one of the candidates of new variable stars from images taken by Ken-ichi Kadota, Ageo City, Saitama, Japan, then confirmed by Seiichi Yoshida.

NSV 12626 is 2.2 arcmin from MisV0738. We have already detected the variability of USNO1200.14174390, R.A. 19h57m41s.082, Decl. +35o47'08".77, 14.4 mag(R), 17.5 mag(B), = IRAS 19558+3538, based on the unfiltered CCD images taken by Ken-ichi Kadota and identified it as NSV 12626 (IBVS 4814). Therefore, MisV0738 is another new variable star.

Taichi Kato pointed out this object is identified with a carbon star CS4580.
